您好我想在我的Android片段中显示谷歌地图。我做的一切都很好，但我不知道这个错误来自哪里。我试图改变不同的东西，但根本不适用于我，下面是代码。
package com.example.nadeemahmad.guitest;
import android.app.Dialog;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;

import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.OnMapReadyCallback;
public class profile extends AppCompatActivity implements OnMapReadyCallback {
GoogleMap googleMap;
ImageButton pr_img_btn;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_profile);
//AIzaSyAjxQKEZc9MHTH3f173Iv21Gw2c6IeUX2U
pr_img_btn = (ImageButton) findViewById(R.id.pr_img_btn);
pr_img_btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent i = new Intent(profile.this,settings.class);
startActivity(i);
}
});
if(googleServicesAvailble()){
Toast.makeText(profile.this,"Perfect!!!",Toast.LENGTH_LONG).show();
initMap();
}
}
private void initMap() {
MapFragment mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.mapFrag);
mapFragment.getMapAsync(this);
}
public boolean googleServicesAvailble(){
GoogleApiAvailability gpa = GoogleApiAvailability.getInstance();
int avail = gpa.isGooglePlayServicesAvailable(this);
if(avail == ConnectionResult.SUCCESS){
return true;
} else if(gpa.isUserResolvableError(avail)){
Dialog dialog = gpa.getErrorDialog(this,avail,0);
dialog.show();
} else{
Toast.makeText(profile.this,"Can't connect to play store",Toast.LENGTH_LONG).show();
}
return false;
}
@Override
public void onMapReady(GoogleMap Map) {
googleMap = Map;
}
}
以下是权限的清单文件。还有元数据和元数据。一切都很好，没有任何错误。

答案 0 :(得分：0)
如果您阅读错误，您就会知道 引起：java.lang.RuntimeException：找不到API密钥。检查它是否在AndroidManifest.xml的元素中
请将com.google.android.maps.v2.API_KEY更改为清单中的com.google.android.geo.API_KEY并尝试。
答案 1 :(得分：0)
正如我在您的日志中看到的那样，您错过了API密钥
Caused by: java.lang.RuntimeException: API key not found. Check that <meta-data android:name="com.google.android.geo.API_KEY" android:value="your API key"/> is in the <application> element of AndroidManifest.xml
将此行放在应用程序标记
中的元数据中
<application
...
...>
...
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzaSyDKymeBXNeiFWY5jRUejv6zItpmr2MVyQ0" />
<meta-data android:name="come.google.gms.version"
android:version="8487000"/>
...
</application>
